“PERVY DUDE ALERT!!! (Not a joke) It’s confirmed: somebody is trying to pretend to be me on Facebook (and maybe other social media platforms) apparently hitting on a lot of different female fans, trying to get their numbers and who knows what else. I’m not joking,” Pratt wrote in a lengthy Instagram caption, along with a screengrab of the account page, which features a profile photo of him from Guardians of the Galaxy. “Please know, I find this behavior reprehensible. If I find out who it is I’ll have their account shut down and seriously would like to punch them right in the GD mouth.”

He also said “many, many people” have told him about this and it’s “not an isolated incident.”
